Introduction SiUS34-801A_b1. Introduction1.1 Safety
ConsiderationsCautions and Warnings
Read these SAFETY CONSIDERATIONS carefully before installing air
conditioning equipment, and be sure to install it correctly. After
completing the installation, make sure that the unit operates
properly during the start-up operation.Instruct the customer how to
operate and maintain the unit. Inform customers that they should
store this Installation Manual with the Operation Manual for future
ref-erence.
Always use a licensed installer or contractor to install this
product. Improper installation can result in water or refrigerant
leakage, electrical shock, fire, or explosion.Meanings of DANGER,
WARNING, CAUTION, and NOTE Symbols:
DANGER ............... Indicates an imminently hazardous
situation which, if not avoided, will result in death or serious
injury.
WARNING ............. Indicates a potentially hazardous
situation which, if not avoided, could result in death or serious
injury.
CAUTION .............. Indicates a potentially hazardous
situation which, if not avoided, may result in minor or moderate
injury. It may also be used to alert against unsafe practices.
NOTE .....................Indicates situations that may result
in equipment or property-damage accidents only. Be sure to read the
following safety cautions before
conducting conducting repair work.
1.1.1 Caution in RepairWarning
Be sure to disconnect the power cable plug from the plug socket
before disassembling the equipment for a repair.Working on the
equipment that is connected to a power supply can cause an
electrical shock. If it is necessary to supply power to the
equipment to conduct the repair or inspecting the circuits, do not
touch any electrically charged sections of the equipment.
If the refrigerant gas discharges during the repair work, do not
touch the discharging refrigerant gas.The refrigerant gas can cause
frostbite.
vii
-
SiUS34-801A_bWhen disconnecting the suction or discharge pipe of
the compressor at the welded section, release the refrigerant gas
completely at a well-ventilated place first.If there is a gas
remaining inside the compressor, the refrigerant gas or
refrigerating machine oil discharges when the pipe is disconnected,
and it can cause injury.
If the refrigerant gas leaks during the repair work, ventilate
the area. The refrigerant gas can generate toxic gases when it
contacts flames.
The step-up capacitor supplies high-voltage electricity to the
electrical components of the outdoor unit.Be sure to discharge the
capacitor completely before conducting repair work.A charged
capacitor can cause an electrical shock.
Do not start or stop the air conditioner operation by plugging
or unplugging the power cable plug.Plugging or unplugging the power
cable plug to operate the equipment can cause an electrical shock
or fire.
Warningviii
-
Introduction SiUS34-801A_b1.1.2 Cautions Regarding Products
after Repair
CautionDo not repair the electrical components with wet
hands.Working on the equipment with wet hands can cause an
electrical shock.
Do not clean the air conditioner by splashing water.Washing the
unit with water can cause an electrical shock.
Be sure to provide the grounding when repairing the equipment in
a humid or wet place, to avoid electrical shocks.
Be sure to turn off the power switch and unplug the power cable
when cleaning the equipment.The internal fan rotates at a high
speed, and can cause injury.
Do not tilt the unit when removing it.The water inside the unit
can spill and wet the furniture and floor.
Be sure to check that the refrigerating cycle section has cooled
down sufficiently before conducting repair work.Working on the unit
when the refrigerating cycle section is hot can cause burns.
Use the welder in a well-ventilated place.Using the welder in an
enclosed room can cause oxygen deficiency.
WarningBe sure to use parts listed in the service parts list of
the applicable model and appropriate tools to conduct repair work.
Never attempt to modify the equipment. The use of inappropriate
parts or tools can cause an electrical shock, excessive heat
generation or fire.ix
-
SiUS34-801A_bWhen relocating the equipment, make sure that the
new installation site has sufficient strength to withstand the
weight of the equipment.If the installation site does not have
sufficient strength and if the installation work is not conducted
securely, the equipment can fall and cause injury.Be sure to
install the product correctly by using the provided standard
installation frame.Incorrect use of the installation frame and
improper installation can cause the equipment to fall, resulting in
injury.
For integral units only
Be sure to install the product securely in the installation
frame mounted on a window frame.If the unit is not securely
mounted, it can fall and cause injury.
For integral units only
Be sure to use an exclusive power circuit for the equipment, and
follow the technical standards related to the electrical equipment,
the internal wiring regulations and the instruction manual for
installation when conducting electrical work.Insufficient power
circuit capacity and improper electrical work can cause an
electrical shock or fire.
Be sure to use the specified cable to connect between the indoor
and outdoor units. Make the connections securely and route the
cable properly so that there is no force pulling the cable at the
connection terminals.Improper connections can cause excessive heat
generation or fire.When connecting the cable between the indoor and
outdoor units, make sure that the terminal cover does not lift off
or dismount because of the cable.If the cover is not mounted
properly, the terminal connection section can cause an electrical
shock, excessive heat generation or fire.
Do not damage or modify the power cable.Damaged or modified
power cable can cause an electrical shock or fire.Placing heavy
items on the power cable, and heating or pulling the power cable
can damage the cable.
Do not mix air or gas other than the specified refrigerant
(R-410A) in the refrigerant system.If air enters the refrigerating
system, an excessively high pressure results, causing equipment
damage and injury.If the refrigerant gas leaks, be sure to locate
the leak and repair it before charging the refrigerant. After
charging refrigerant, make sure that there is no refrigerant leak.
If the leak cannot be located and the repair work must be stopped,
be sure to perform pump-down and close the service valve, to
prevent the refrigerant gas from leaking into the room. The
refrigerant gas itself is harmless, but it can generate toxic gases
when it contacts flames, such as fan and other heaters, stoves and
ranges.When replacing the coin battery in the remote controller, be
sure to dispose of the old battery to prevent children from
swallowing it.If a child swallows the coin battery, see a doctor
immediately.
Warningx
-
Introduction SiUS34-801A_b1.1.3 Inspection after Repair
CautionInstallation of a leakage breaker is necessary in some
cases depending on the conditions of the installation site, to
prevent electrical shocks.Do not install the equipment in a place
where there is a possibility of combustible gas leaks.If a
combustible gas leaks and remains around the unit, it can cause a
fire.
Be sure to install the packing and seal on the installation
frame properly.If the packing and seal are not installed properly,
water can enter the room and wet the furniture and floor.
For integral units only
WarningCheck to make sure that the power cable plug is not dirty
or loose, then insert the plug into a power outlet all the way.If
the plug has dust or loose connection, it can cause an electrical
shock or fire.
If the power cable and lead wires have scratches or have
deteriorated, be sure to replace them.Damaged cable and wires can
cause an electrical shock, excessive heat generation or fire.
Do not use a joined power cable or extension cable, or share the
same power outlet with other electrical appliances, since it can
cause an electrical shock, excessive heat generation or fire.
CautionCheck to see if the parts and wires are mounted and
connected properly, and if the connections at the soldered or
crimped terminals are secure.Improper installation and connections
can cause excessive heat generation, fire or an electrical
shock.
If the installation platform or frame has corroded, replace
it.Corroded installation platform or frame can cause the unit to
fall, resulting in injury.Check the grounding, and repair it if the
equipment is not properly grounded.Improper grounding can cause an
electrical shock.xi
-
SiUS34-801A_bBe sure to measure the insulation resistance after
the repair, and make sure that the resistance is 1 ohm or
higher.Faulty insulation can cause an electrical shock.Be sure to
check the drainage of the indoor unit after the repair.Faulty
drainage can cause the water to enter the room and wet the
furniture and floor.

Use the above tables to determine the capacities of indoor units
to be connected. Make sure the total capacity of indoor units
connected to each outdoor unit is within the specified value
(Btu/h). The total capacity of connected indoor units can be within
a range of 50 to 200% of the rated
capacity of the outdoor unit (rules apply). In some models, it
is not possible to connect the maximum number of connectable indoor
units.
